style="font-size:16px;">在啟閉軟密封閘閥時(shí)，千萬不應(yīng)關(guān)閉過死，只要達(dá)到止水效果即可，否則不易開啟或襯膠剝離。某閥門廠家，在閥門試壓檢驗(yàn)時(shí)，使用扭力板手來控制關(guān)閉的程度，作為自來水公司的閥門操作人員也應(yīng)效仿此種啟閉方法。閘閥和蝶閥在管道使用中都是起開關(guān)，調(diào)節(jié)流量的作用。當(dāng)然在蝶閥和閘閥的選配過程中還是有方法的。在供水管網(wǎng)中為了降低管道覆土深度，一般口徑較大管道選配蝶閥，對(duì)覆土深度影響不大的，力求選配閘閥，但是同樣規(guī)格的閘閥價(jià)格又比蝶閥的價(jià)格高。至于口徑的分界線應(yīng)各地按具體情況考慮。從近十年使用情況而言，蝶閥出現(xiàn)的故障比閘閥高，因此在條件許可的情況下，擴(kuò)大閘閥的使用范圍是值得關(guān)注的。軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機(jī)械加工，不使用密封銅環(huán)，節(jié)約有色金屬。</span>

style="font-size:16px;">由于蝶閥閥板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)蝶閥可用于帶懸浮固體顆粒的介質(zhì)，依據(jù)密封件的強(qiáng)度也可用于粉狀和顆粒狀介質(zhì)。蝶閥是用圓盤式啟閉件往復(fù)回轉(zhuǎn)90度左右來開啟、關(guān)閉和調(diào)節(jié)流體通道的一種閥門。蝶閥不僅結(jié)構(gòu)簡單、體積小、重量輕、材料耗用省，安裝尺寸小，而且驅(qū)動(dòng)力矩小，操作簡便、迅速，并且還可同時(shí)具有良好的流量凋節(jié)功能和關(guān)閉密封特性，是近十幾年來發(fā)展**快的閥門品種之一。特別是在美、日、德、法、意等工業(yè)發(fā)達(dá)國家，蝶閥的使用非常***．其使用的品種和數(shù)量仍在繼續(xù)擴(kuò)大，并向高溫、高壓、大口徑、高密封性、長壽命、優(yōu)良的調(diào)節(jié)特性以及一閥多功能方向發(fā)展，其可靠性及其他性能指標(biāo)均達(dá)較高水平，并已部分取代截止閥、閘閥和球閥。隨著蝶閥技術(shù)的進(jìn)步。在可以預(yù)見的短時(shí)間內(nèi)，</span><span

style="font-size:16px;">在項(xiàng)目上是用對(duì)夾，還是支耳，還是法蘭。這個(gè)問題可以簡化為是用對(duì)夾還是法蘭。法蘭比對(duì)夾的一個(gè)重要的優(yōu)勢(shì)就是可以單夾在一側(cè)管道上，可以做盲板使用，也可以在另一側(cè)需要維修，更換時(shí)，只需要關(guān)閉閥板，卸掉需施工側(cè)的管道即可。對(duì)夾蝶閥就做不到這個(gè)功能。螺紋孔的支耳和法蘭蝶閥的選擇。提到這個(gè)討論，主要是現(xiàn)在一個(gè)特殊的垂直行業(yè)，數(shù)據(jù)中心行業(yè)。因?yàn)檫@個(gè)行業(yè)的環(huán)形管網(wǎng)有大量的蝶閥的設(shè)計(jì)，并且有這較高的安全要求，每一段都能快速關(guān)斷并在不影響系統(tǒng)的情況下進(jìn)行維修。因此有大量的支耳和法蘭蝶閥應(yīng)用在這個(gè)市場。支耳能得以應(yīng)用是有兩個(gè)原因，首先是它能起到單夾在一側(cè)管道上的功能，二是價(jià)格便宜。所以很迎合市場的需求。我們以常見的DN400口徑為例，支耳的厚度在102mm，因此單側(cè)的受力是實(shí)際上是靠不到5公分的螺栓來支撐，對(duì)螺栓的疲勞強(qiáng)度影響較大，使用可靠性要遠(yuǎn)遠(yuǎn)低于法蘭連接形式。所以不建議在項(xiàng)目上大量使用支耳蝶閥。</span>
